Totally Agree.

I think conventional airplanes have reached their limit. That does not mean airplanes cannot become more efficient. BWBs (Blended Wing Body) are more efficient than traditional aircraft. They have increased payload and fuel efficiency. Kind of like a merging of a flying wing (B2 Bomber) and traditional swept wing (747/777).

"Blended wing body has lift-to-drag ratio 50% greater than conventional airplane."
http://en.wikipedia.org/wiki/Blended_wing_body

Boeing/NASA are currently exploring BWB with the X-48.

> Would have loved to get a "push" notification from AAPL regarding this..

If you managed to miss the iOS 6/iPhone 5 announcement, a push notification wouldn't have helped. Also, this is standard practice, happens every year, and is mentioned in the dev notes before you download the beta.

> Seems like Apple is no longer signing the iOS 5.1.1 ipsw - this is ridiculous...

Or standard practice and mentioned in the developer notes when you download the beta...

> On another note..I cannot restore to my iOS6 (beta) backup with the real iOS6..

You're mad that there was a bug in a developer-only beta? Did you ever stop to consider that if you're going to sarcastically chide Apple over a beta issue, maybe you aren't the type to be running betas?
It's the reason your site's fonts look so terrible in Chrome for Windows.

Nothing says built on a mac like jagged webfonts on Windows.

Edit:

Here's some more info on the issue, to (hopefully) be more useful:

"Using Web fonts in your design requires thorough testing on as many different browsers and platforms as possible, with a close look at various options for rendering text. If the screen display is of poor quality and lacks subpixel rendering, then opt for graceful degradation by serving system fonts to older browsers and OS. Conditional comments are the easiest way to exclude older browsers and operating systems from style sheets with Web fonts. Of course, JavaScript is a more elegant way to detect whether a client’s subpixel rendering is turned on."

It's important to understand the characteristics of various sorting algorithms so you can choose the best one

I disagree - most languages offer a sort function which is nealry optimal in the average case. You very rarely choose unless you are doing something where the sort performance is extremely important.

However, uunderstanding various sort algorithms and their intricacies is a great way to demonstrate fundamental algorithm design as well as some data structures. This is why it's important - so when you do write code, you come with a huge amount of insight into how to go about it.
I do not think that this is correct. Ideas are a dime a dozen. I think that execution is the most important aspect of a startup. The idea might actually not matter all that much, indeed the underlying idea might change quite radically over the lifetime of the startup.
If anything, that just goes to show how difficult it is to convey the right tone. Even when you're fully conscious of it, you may still fall for certain biases.
Not connected to the tutorial but I was trying to look at their other posts and I seem to get redirected to their learn.thoughtbot.com where they show their books, webcasts, and workshops which isn't bad but I just want to read their other posts.

Does anyone know how?
I'm not sure you're quite right about 1. Depending on what you mean exactly. For example, insertion sort is O(n^2) but mispredicts O(n) times. That doesn't seem often to me.

There are (artificial) mergesorts that execute O(nlogn) branches but also mispredict O(n) times.
See for example
"branch mispredictions don't affect mergesort:"
http://www.cphstl.dk/Paper/Quicksort/sea12.pdf

In the case of 2. I agree, although compiler support still isn't great -- I think. For almost all cases (integers, floats, strings) radix sorting would be even better -- fewer instructions, no comparison branches.
What about if it isn't OSS? Do you like more reference style docs (i.e. this method takes arguments x, y, z, returns a string) or narrative (i.e. to accomplish goal x, you'll need to do y and z like this ...)?
That would be amazing. Can you email me at max@kera.io?

"Placebo effect has no meaning in this context. Placebo effects are caused by mind rather than a substance. In this case, the entire treatment is in the mind."

If you're a dualist, then okay. But I'm not. And since the mot compelling evidence of the effect of meditation so far presented involves structural changes to the brain, I think you just talked yourself out of a case.

"There are many, many, many studies on the benefits and effects of meditation. If you haven't found any, it's because you are not looking."

Within the context of improving your ability to withstand distraction? Most everything linked here is almost invariably about structural alterations which are surely significant, but not tied to any specific effect.

What constitutes as a "bully comment"? What doesn't qualify as a "bully comment"? What would stop someone from abusing this privledge and removing perfectly legitimate negative comments? Who decides what is truth and what is trolling?

Also how do you propose a team be assembled to combat online mean statements? I think there's more junk in online comments than there is useful information.

I hope you can appreciate how that idea starts to get really sticky really quickly.
Cults have rules like that to cut you out of your old life, but in this case I think it's a legitimate desire to eliminate ALL distraction. I did one of their retreats many years ago and concluded that the changes in my internal life that could only happen in such an environment.

For example, after a few days my internal monologue petered out and for the first time I realized that a good portion of my mental activity was normally devoted to thinking about things I was going to say later on. Once I was out of the habit of talking all the time, I stopped cooking up little quips and observations about everything and really felt an expansion of non-verbal thinking.

So, although I had my doubts about the place going in, I left feeling that 10 days of intense internal focus was the only possible way to reach the insights I'd had, and that I was glad I'd done it. The months afterwards (while I kept up the practice, before I got "too busy"), were the most contented of my life.
I'm fully aware I've been in the industry for 6 months. I said so, very clearly, in my post. I wanted very much to make sure that people knew that I have only been in the industry a short time but this was my experience so far. Frankly I find the idea that just because someone has a small amount of experience their opinion is invalid ridiculous and insulting. The only reason a newcomer's opinion might not be worth listening to is if they are pretending they have a wealth of experience. At no point did I do that.

I can only assume that the 2 years as a movie usher you're referring to is the 2 years as a teenager I spent volunteering at my local non-profit cinema whilst also doing my A-level exams and working a part-time job. I'm pretty sure the only place this is even mentioned online is on my LinkedIn profile, at the absolute bottom, after you would have scrolled past the various jobs I have held in sales and marketing, and local government (where as I mentioned in the post, I did in fact experience some sexism).

As for the final comment, I did indeed reread the article several hours later, before I wrote my post, to ensure that I still felt the same way. I actually found MORE that I disagreed with on a second read-through.
yeah, Brian's awesome. He signed up for Kera a few months ago so we've been chatting for some time.
Yes and no. It could be that there's a misunderstanding of what meditation is, or is good for.

Sometimes it's best to use your time to actually practice your football skills, go out on the field and play; or else spend that time planning the next game, doing strategy and stuff like that.

But other times it's best to go to the gym and lift weights. That may seem like a waste of time for a football player, but it actually makes him stronger, so he gets better results in the game - because he engaged in a seemingly unrelated activity. Strangely enough. ;)

Same with washing dishes. Sometimes you use that time to draw plans for the future, advance the theoretical side for the projects you're working on ("play actual football with your team mates in the field"). Other times it's best to use those moments to meditate ("lift weights at the gym"). Both are useful, and in fact it's best if you practice both, at different times.

My intuition is that the recursion shouldn't hurt getting useful results, even if the simulation was allowed to proceed past the point where such a simulation was developed (which they may not have), in a manner akin to the resolution of Zeno's Paradox. Though there's likely a bound on how many layers deep we can go, but my quantum information theory isn't what it used to be so I have to hand wave my conjectures.
Hmmm, an article that seems to pine for the days of true client/server applications...

Oops, someone (the author) forgot about AOL, which was founded in 1985 and began mailing floppy disks to people in 1993 (http://techcrunch.com/2010/12/28/aol-floppy-disk/). That is when and where I had my first social web experience (it was in an AOL chat room, specifically). The company and the "social web" boomed from there, so much so, in fact, that eventually AOL bought Time Warner. It was the largest merger ever, at the time (http://money.cnn.com/2000/01/10/deals/aol_warner/). And it flopped, but that beside the point :)
That is retconning "social web" to cover every kind of interaction. Applied hindsight-bias. Before the web, there were boards on services like CompuServe, The Source, AOL, and others, that simply had names that you told other people. It's not a new technology to email someone you're going to the mall when before email you would just tell them over the phone or whatever.

Perhaps "crap sort" is appropriate, in that the performance of the algorithm itself is crap, and the name also evokes similar intuitive parallels to "bubble sort", since (as we know) crap floats to the top just as bubbles do.
The problem though is that (good) execution is also critical for all businesses. We're looking for a unique characteristic to identify a startup from "normal" businesses.
I'm thinking the same thing. These aren't website passwords, they need to be recoverable by an administrator. I'm sure this is by design.
While I applaud your backhanded complimenting of the article by your assertion that it could and should be the focus of at least two PhD dissertations and possibly a 300+ page book, I would suggest at the same time that perhaps you might be setting the bar a bit high here.

I mean, take as an example your own message, in which you simply fling a few trite accusations at the author without, yourself, doing any work to substantiate or expand on them. Perhaps you would consider extending the privilege you so freely used to others.

More room for vulnerabilities, less consistent user experience, and all the other annoyances Flash and Java applets bring to the table. Sounds great.
A startup is whatever you think it is. There is no solid definition. I imagine most people will agree that a startup is always a newly formed business, which is probably geared to "grow" at a fast pace, and is probably not something traditional or brick and mortar.

The rest is just trying to figure out who you don't want calling themselves a startup.

(And by writing this I have joined the others in attempting to define this word.)
Also, this is just one type of startup. Thus the inclusion of the term "Lean". Not all startups have or need to have the lean characteristics.
News FLASH: Microsoft doesn't create software, despite all appearances [VMS++, Spyglass etc.] -- neither does that Italian restaurant make its living off of pasta [capo dei capi!]. VW doesn't make cars. It creates car factories. The cars are just byproducts. Intel doesn't make CPUs. It makes fabs [fabrication plants]. CPUs are byproducts (they were RAM, and could also very well be ...well FLASH).
I'm not sure I buy this as a lesson. Choosing between two asymptotically (very) different algorithms (probably linear vs quadratic in your case) isn't really a performance tweak in my book, even though as you point out it wasn't dominant in your case.

Even the world's slowest disk will be faster than a CPU executing a sufficiently silly algorithm.
a) The article at no point denies sexism exists.

I think Paul Graham meant it to be a necessary condition to be a startup, but not an exclusive one. Pretending otherwise is just a camouflaged straw man.
For sure, there are a few trailer parks around here you can rent in. Best way is to come work for a start up or work for a bigger tech company. Go to meetups, go meet VCs, network.

So the answer is come, just move here, don't wait. I wish I had moved back in 1998 when I had the chance instead of 2012.
In a quaint bit of online archaeology, Douglas Hofstadters' Metamagical Themas describes his experiences using some of the early Unix communications tools, particularly talk (predecessor to IRC) and the dynamics it triggered. They're very, very similar to what emerged later as IM and SMS became prevalent.

Modulo the rather smaller share of users in possession of PhDs in mathematics, computer science, or other technical disciplines.
> An expensive watch [...] tells the time about as accurately and about as reliably as a mid-priced or cheap watch.

Actually, there's a huge difference in the accuracy of high-end and cheap watches. The cheap watches are way better.
Honestly, I'd rather have a well commented example application that utilizes the framework with decent API documentation. So a little bit of both. The APIs are hopefully written well enough that things are fairly self documenting.

Maybe a couple of different example applications to serve different goals would be helpful as well instead of one monolithic project.

I've just never really been big on blog posts that are showing me code and why things are there, when that can all be done within the project itself and I can run it, maybe setup breakpoints and hack around. I can get up and running faster that way, and I hate high barriers to entry when I'm looking to play around with something.

Somebody posted here recently about the a55-hole that should be fired, the senior guy who is negative and disagrees with everyone, the wet blanket.

Then we get this - they should be praised, encouraged. I'm not so sure. Paralysis by Analysis used to be a popular phrase. Sure some kind of brainstorming of negatives is good. But we have to assume we'll overcome obstacles and not be crushed by them.

Back in the day I wanted to rewrite an OS to use a new memory model the i286 supported. I surveyed the code and presented the action list. Project never got off the ground - too much work.

Another senior Engineer took a different tack - he just started coding in his office. In 6 months he had recruited others to his effort, gotten funding, and completed the project. All because he didn't show people the obstacles, instead he promoted the advantages.

I think optimism is the reason we do anything.

Web-apps (and the WWW browsers making them possible) were supposed to be the solution to the portability problem. They're not and layering more crap on top of them is not the solution either.

Leaving other (e.g., security) issues aside, this plan would make things far worse. Would new processors be second-class citizens? Would WWW browsers have to (incompatibly) transform themselves into emulators/VMs for the different kinds of "native code" found on the Wild Wild Web?

Most importantly: Would this be the first step toward a closed/proprietary WWW? "View Source" is still useful in this regard, despite the amount of useless JavaScript obfuscation we're seeing today.

So that's a good start. Is that all we have? I see some credible studies on pubmed (and plenty of studies with all the markers of being useless, some outright mentioning "CAM"-friendly goals in the abstract), but most of them involve things like mindfulness meditation as a method of improving performance on X, where X is some sort of motor-coordination task.

What the study you cited suggests interesting research could be done. My big question is that is any sort of hard focus activity of the same quality as meditation?
Thank you so much for the kind words. I'll follow up with an email shortly.

I like this idea! It reminds me of this page http://mozilla.github.com/pdf.js/web/viewer.html which loads a JS-based PDF reader and then uses it to render a PDF in your browser. It could be expanded to do a lot more than static documents - in fact it seems to echo the ideas that Alan Kay has been working on for decades. http://www.drdobbs.com/architecture-and-design/interview-wit... "Binstock: Still, you can't argue with the Web's success.

Kay: I think you can... go to the article on Logo, can you write and execute Logo programs? Are there examples? No. The Wikipedia people didn't even imagine that, in spite of the fact that they're on a computer.... Go to a blog, go to any Wiki, and find one that's WYSIWYG like Microsoft Word is. Word was done in 1974. HyperCard was 1989. Find me Web pages that are even as good as HyperCard. The Web was done after that, but it was done by people who had no imagination. They were just trying to satisfy an immediate need.... what you definitely don't want in a Web browser is any features.

Binstock: "Any features?"

Kay: Yeah. You want to get those from the objects. You want it to be a mini-operating system, and the people who did the browser mistook it as an application. They flunked Operating Systems 101.... I mean, look at it: The job of an operating system is to run arbitrary code safely. It's not there to tell you what kind of code you can run."
I think Alan Kay made a comment of the same kind about the current web. Compared to an old tradition to embed an 'interpreter' ahead of any data.
Several years ago, I had an exam question asking what sort algorithm one should use in different situations, one of which was "automatically sorting a bibliography list when printing a research paper". I answered that while bubble sort is normally terrible, it's a great choice here if you're hand-rolling a sort instead of using a library. The data set couldn't possibly be large enough for the sort run-time to matter, particularly in comparison to printing time, and it's the simplest to correctly program.

There are circumstances in which bubble sort really is that bad, but on small data sets that are already disk/network/peripheral IO bound, it's just fine.
If I'm starting a flower business, is that a startup? No. I'm just starting a business. Selling flowers is a proven business model.

The difference between starting a business or a startup is that a startup is trying to solve a unique problem. It often tries to do this through the use of technology.

If I think I might have found the cure for cancer which could lead to a billion dollar company but I need to do 5 years of research, that's a startup! No bank is going to give me a loan for this so I need investors who believe in my vision.
